I like to run 91 or 94. Costs a little more but feels like it runs better. (maybe just in my head) but hey I figure theres gotta be a reason for it. why use Race gas at a track otherwise? If I get a chance I may one day tune for 94.
Its like synthetic vs non synthetic. Sure its not needed but it is better.

Not all race cars use race gas - you're logic is a little fuzzy there - putting a roll cage and slicks on a Miata does not mean I need to go fill it with 110. Race gas is used for special applications like some purpose-built cars that run very high compression, classic cars, etc., not because of a universal law that says higher octane = go faster. If a car can race on normal street octane level fuels, it generally will - the price of race grade fuel is too absurd to do otherwise. Plus, race gas can contain additives that aren't exactly healthy to run through a normal street car (if you're thinking in terms of a track day visit).
There are situations where synthetic is the only option. You're totally right in terms of the Lancer, though - it's not needed, but it is better.

Yeah I guess you're right with the tune I just feel like she runs smoother. Maybe its in my head. Guess I gotta get it tuned .
How about keeping fuel pumps clean and what not? Sure it wont help at all?
Either way in my head it feels better so I'll prob continue wasting my money lol

high octane fuel burns slower so you can tune for that by advancing timing, and it is also more compressible so you can run a leaner AFR without knocking...factory tune and stock compression ratio, premium fuel will make your car slower before it makes it faster, and like nj_08_gts said, you'll get incomplete combustion...
since i last posted here, i turbocharged my engine, and i'm still running 91...
